The Variation Of Plasma BNP Level Of Acute Myocardial Infarction As Well As Their Clinical Characteristic After Percutaneous Coronary Intervention

Objective:The study investigated the variation of plasma BNP level of ST-segment Elevation Myocardial Infarction patient and Non-ST-segment Elevation Myocardial Infarction patient as well as their clinical characteristic after percutaneous transluminal coronary intervention.Methods:Collecting 126 acute myocardial infarction patients that taken place for the first time in emergency department from January 2015 to December 2015,according to the variation of electrocardiogram on admission,all the enrolled patients were divided into 72 consecutive patients with STEMI and 54 consecutive patients with NSTEMI.Reference to the outcome of coronary angiography,meanwhile,all the patients were divided into single vessel lesion group,two-vessel lesion group and three-vessel lesion group.The contral grounp comprised 8 males and 12 femals,age and gender mached.The plasma BNP was measured respectively in the 24 th hour of on admission and the 7th of after PCI,study the relation of the variation of BNP level and clinical characteristic.Results:In the 24 th hour of on admission,the plasma BNP level of single vessel lesion group,two-vessel lesion group and three-vessel lesion group with STEMI were all significiantly higher than the patients with NSTEMI(P<0.05).In the 7th of after PCI,the plasma BNP level of single vessel lesion group with STEMI and NSTEMI was no statistical significance(p>0.05),the plasma BNP level of two-vessel lesion group and three-vessel lesion group with STEMI Were lower than the patients with NSTEMI(P<0.05).Conclusion:The plasma BNP level and clinical traits of acute myocardial infarction patients after the emergent PCI were also very beneficial to infer the state of disease accurately,rank the risk stratification and assess the long prognosis.
